A hypothetical binary eutectic phase diagram of A-B is shown below. An alloy with 5 wt.% B solidifies with no convection. Assuming steady state, the critical temperature gradient (in K mm-1) required to maintain planar solidification front is: _______ (round off to nearest integer).
Given: Diffusivity of B in liquid = 10-9 m2 s-1 Velocity of solidification front = 4 µm s-1

Correct : 100
